To aZZ whom it may concern.-

Be it known that we, JAMES N. I\L\RTIN and WILLIAM HAMILTON HARRIS,citizens of the United States, residing at Newberry, in the countyofNewberry and State of South Carolin a, have invented certain new anduseful Improvements in Chairs and Lock-Joints for Railroad-Rails; and wedo declare the following to be afull,clear, and exact description of theTO invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which I 5 form a part of this specification.

This invention relates to an improved chair and lock-joint forrailroad-rails; and it has for its objects to securely fasten the railsat their junctures and form a rigid seat for the same, as more fullyhereinafter specified, and

specificallv pointed out in the claims.

Referringto the accompanying drawings, forming part of thisspecification, Figure 1 represents a perspective view showing our in- 25 vent-ion complete with the parts connected.

Fig. 2 represents a similar view showing the parts detached, and Fig.represents a transverse vertical sectional view of our invention. Theletter A indicates that portion of the 0 device COnstltul'll'ig' thechair for the rails, which is constructed, preferably, of cast metal,with seats :1 at opposite ends of the rails 0. Midway between the endsof the chair is a space, I), in which the ends of the rails set and inwhich the lockingdevicesare applied. I The flanges of the rails at theportions correi spondin to the seats I are cut away, iiidicated by theletter E, leaving lugs I at the adjoining ends of the rail, which setunder the recesses G, formed at one end of the locking-space, so as tosecurely fasten the rails with their abuttin ends in contact. At oneside of the locking-space is a web, H, having a perforation or opening,I, through which 5 the locking-bolt K passes.

The said bolt also 1 passes through a detachable locking-plate, L,

which sets in the open side of the lockingtndinal direction, relievingthe joint of all strain, while at the same time the rails are securelylocked therein.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is

1. A chair for railroad-rails having seats with an intermediatelocking-space recessed at one end, in which the abutting ends of therails are secured, substantially as shown and described.

2. The combination, with the chair having seats for the rails andintermediate lockingspace and recesses G, of the rails provided withlugs at their ends adapted to fit in the said locking-space, andrecesses to hold the rals in the chair, substantiall as specified.

The combination, with the chair having seats for the rails and anintermediate lockiug-space, and the perforated web at one side of saidspace, of the detachable locking-plate, the screw bolt and nut, and therails having cutaway flange portions, whereby the rails are securelyfastened, and at the same time the proper expansion and contraction ofthe rails are provided for, substantially as specified. In testimonywhereof we a ffix our signatures in presence of two witnesses.
